# Belongs to category:

# Description and specifications:
Microscope arm with focusing knobs and fine and coarse focus for microscopes based on the N-117M / DN-117M models.

The N-117M / DN-117M microscope is a fairly good laboratory microscope manufactured at the Chinese NYO factory and sold worldwide under various names. These microscopes are known and sold, among others, as:
- Delta Optical Genetic Pro (mainly in Poland)
- AmScope B340 / T340 (mainly in the USA and the rest of the world through Amazon)
- Labtron LEM-C10 / C11 / C12 (mainly in the UK)
- Sigeta MB-207 (mainly in Ukraine)
- Boeco Germany BM-117 (mainly in Germany)
- BestScope BS-2020 (mainly in the USA, shipped worldwide)
- Brunel N117M (mainly in the UK)
- Apex N-117M (mainly in the UK)
- Surgifield SM-DN-117M (mainly in Nigeria and West Africa)
- Eurotech DN-117M (mainly in Peru)
- Biocare DN-117M (mainly in Peru)
- Viresa N-117M (mainly in Mexico)
- Eurolab DN-117M
- Nexcope N-117M
- Novel N-117M

This is certainly not a complete list of names – many sellers give the microscopes they sell their own names without a model number (just like Delta Optical in Poland).

The N-117M model has a binocular or trinocular head, while the DN-117M model has a built-in digital USB camera (hence the “D” at the beginning of the name, for “Digital”) – but the stand is shared by both models, so fits both models.

# Examples of use
- For those who have a damaged component in their microscope: focusing knobs, fine focus or coarse focus mechanism
- If you want to use these mechanisms in another microscope model, if it's compatible
- If you want to have a spare focusing block
